Here is the result of combining your two favorite things the arcade Pong and fascinating Portals.
Play the result of a wonderful combination.
Outsmart the ferocious AI. Outsmart your friends. Aim for the right portal at the right time and look at the face of your flabbergasted opponent.
Play through three modes Sane, Mildly Sane and Insane with increasing number of portals.
And remember "With great Portals comes great Action".
Enjoy.
